sPnIPIcA'I-ION forming part of Letters Patent No. 455,636, date July 7,1891.

Application filed September/1, 1890. Serial No. 363,938. (No model.) I

To all whom t -may concern:

Be it known that we, CHARLES J. MCKEN ZIE and DAVID M. l\lIKEsELL, of Wauseon, in the county of Fulton and State of Ohio, have invented anew and Improved Pump, of which the following is a full, clear, and exact The object of the invention is to provide a new and improved pump which is simple and durable in construction, very effective in operation, and serves as a double-acting force and lift pump.

The invention consists of certain parts and details and combinations of the same, as will be fully describedhereinafter, and then pointed o ut in the clai i Reference is to be had to the accompanying' drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional side elevation of the improvement. Fig. 2 is a sectional plan view of the same on the line 2 2 of Fig. 1, and Fig. 3 is a similarview of the same on the line 3 3 of Fig. l.

The improved pump is provided with a cylindrical barrel A, having a bottom B provided with a number of openings B', arranged in a circle and adapted to be closed on the inside by a ring-valve C, iitted to slidevertically onbolts C', secured on the bottom B.

Within the barrel A is fitted to slide a recessed plunger D, secured on a hollow stem E in communication with the recess of the plunger and adapted to pass through a head F, held on the upper end of the barrel A. 'The head F screws in the lower end of a tube G, extending tothe outside of the Well in which the pump is located and serving asianV exitpipe for the water. On the extreme upper end of the hollow vertical stem E is arranged a check-valve H, and the said upper end of the stem is rigidly connected with a rod or pipe I, extending through the tube G and connected with suitable mechanismfor imparting an up-and-down motion to the said rod, so as to work the plunger D in the barrel A.

Above the plunger D is arranged on the inside of the wall of the barrel A a valve J, operating over openings A', formed in the wallv of the barrel, as is plainly shown in Fig.

The valve J is preferably made in the Vform ofla disk shaped at the inner face to ter against the top and bottom in order to close the openings D3 and D4, respectively. Between the top and bottom D' and D2,re spectively, are arranged split rings. D5, held in place at their middle by pins D, fitting intothe lianges of the top and bottom D and D2.

In the head F is -arranged a packing L, provided with a shell N, the inner surface of which is conical, as is plainly shown in Fig. l, and is adapted to be engaged by a series of segmental wedges O,pressing with their inner straight sides of sectional packing-rings P, held against the exterior of the hollow stem E. One or more coil-springs Q are arranged 'on top of the wedges O, the upper ends of the Said springs pressing against the under side of the headF, as is plainly shown in Fig. l. The lowermost packing-ring P rests on a fixed ringjN arranged or formed in the bottom. of the shell N. The uppermost packingring P is engaged by an annular projection F', formed on the head F, and also engaging the inside of the Walls O. The shell N is providedl with an exterior thread, part of which screws' in the barrel A and part in the head F, so that the latter is united by the said shell with the casing A, and at the same time the head F 4forms a gland for the packing L.

The operation is as follows: The barrel A is submerged in the water in the well, and when the plunger D is moved upward the ring-valve C opens the openings B' to permit the water to lill the lower part of the barrel. The Water above the plunger D on the barrel A presses through the openings Dato open IDO . any desired height.

the ring-Valve K and to pass into the recessed plunger, and from the latter through the hollow valve-stem E and past the check-valve H to the exit-tube G, thevalves K and J remaining closed during the upward movement of the plunger. the plunger the ring-valve C closes and the water in the lower part of the barrelpresses through the openings D4 to open the ring- Valve K and to pass into the recess of the plunger, and from the latter through the hollow stem E, past the check-valve H to the tube G. At the same time the valve J opens inward, so that Water from the well rushes through the openings A into the upper part of the barrel and fills the same. The Valves K and C remain closed during the downward stroke of the plunger. Thus it will be seen that a continuous stream of water is pumped on the up and down stroke of the plunger, and that the Water can be lifted or forced to It will further be seen that the cylindrical barrel A permits of plac- On the downward stroke of ing the same into a fixed pipe such as are usually found in drill-wells, as the said barrel has no projections whatever on the outside.
